The concept of authenticity plays an important role in how people reason about objects, other people, and themselves. However, despite a great deal of academic interest in this concept, to date, the precise meaning of the term, authenticity, has remained somewhat elusive. This paper reviews the various definitions of authenticity that have been proposed in the literature and identifies areas of convergence. We then outline a novel framework that organizes the existing definitions of authenticity along two key dimensions: describing the (...) type of entity that is evaluated and describing the source of information that is consulted. We argue that this convergence across a number of papers, and more importantly, across a number of domains, reflects significant progress in articulating the meaning of authenticity. We conclude by suggesting new avenues for research in this area, with particular attention toward psychological process. (shrink)

This paper examines people's reasoning about identity continuity and its relation to previous research on how people value one-of-a-kind artifacts, such as artwork. We propose that judgments about the continuity of artworks are related to judgments about the continuity of individual persons because art objects are seen as physical extensions of their creators. We report a reanalysis of previous data and the results of two new empirical studies that test this hypothesis. The first study demonstrates that the mere categorization of (...) an object as “art” versus “a tool” changes people's intuitions about the persistence of those objects over time. In a second study, we examine some conditions that may lead artworks to be thought of as different from other artifacts. These observations inform both current understanding of what makes some objects one-of-a-kind as well as broader questions regarding how people intuitively think about the persistence of human agents.

When Christiaan Huygens prepared the 1686/1687 expedition to the Cape of Good Hope on which his pendulum clocks were to be tested for their usefulness in measuring longitude at sea, he also gave instructions to Thomas Helder to perform experiments with the seconds-pendulum. This was prompted by Jean Richer's 1672 finding that a seconds-pendulum is 1 1/4 lines shorter in Cayenne than in Paris. Unfortunately, Helder died on the voy¬age, and no data from the seconds-pendulum ever reached Huygens. He nevertheless (...) did receive data from his clocks on the return-voyage from the Cape of Good Hope to Texel. When he first calculated the ship's course according to these data, it appeared to have gone straight through Ireland. He then tried introducing a correction to the data, based on an idea he had previously entertained as a possible explanation of Richer's finding: he corrected the observed time to com¬pen¬sate for a reduction in the effect of gravity from the Poles to the Equator resulting purely from the Earth's rotation. His newly calculated course convinced him that this rotational effect is the sole source of any variations in gravity with latitude. This paper examines Huygens's correc¬tions to the data and his reasoning from the new course to the conclusion that nothing else causes a variation in gravity. In the process, we show that Huygens had cogent empirical reasons to reject Isaac Newton's theory of universal gravity, which predicted a some¬what larger variation in gravity. (shrink)

Incommensurability between successive scientific theories—the impossibility of empirical evidence dictating the choice between them—was Thomas Kuhn's most controversial proposal. Toward defending it, he directed much effort over his last 30 years into formulating precise conditions under which two theories would be undeniably incommensurable with one another. His first step, in the late 1960s, was to argue that incommensurability must result when two theories involve incompatible taxonomies. The problem he then struggled with, never obtaining a solution that he found entirely satisfactory, (...) was how to extend this initial line of thought to sciences like physics in which taxonomy is not so transparently dominant as it is, for example, in chemistry. This paper reconsiders incommensurability in the light of examples in which evidence historically did and did not carry over continuously from old laws and theories to new ones. The transition from ray to wave optics early in the nineteenth century, we argue, is especially informative in this regard. The evidence for the theory of polarization within ray optics did not carry over to wave optics, so that this transition can be regarded as a prototypical case of discontinuity of evidence, and hence of incommensurability in the way Kuhn wanted. Yet the evidence for classic geometric optics did carry over to wave optics, notwithstanding the fundamental conceptual readjustment that Fresnel's wave theory required. (shrink)

A particular research program on mental imagery is defended against certain sweeping methodological criticisms that have been advanced against it. The central claim is that the approach taken in the program is an appropriate response to the problem of doing empirical research in a theoretical vacuum, and that when it is viewed in this perspective, the criticisms are not merely unfounded, they are inappropriate. The argument for this claim is developed by first describing the program and then analyzing the methodological (...) rationale behind it. (shrink)

Sir Isaac Newton was one of the greatest scientists of all time, a thinker of extraordinary range and creativity who has left enduring legacies in mathematics and physics. While most famous for his Principia, his work on light and colour, and his discovery of the calculus, Newton devoted much more time to research in chemistry and alchemy, and to studying prophecy, church history and ancient chronology. This new edition of The Cambridge Companion to Newton provides authoritative introductions to these further (...) dimensions of his endeavours as well as to many aspects of his physics. It includes a revised bibliography, a new introduction and six new chapters: three updating previous chapters on Newton's mathematics, his chemistry and alchemy and the reception of his religious views; and three entirely new, on his religion, his ancient chronology and the treatment of continuous and discontinuous forces in his second law of motion.

Sir Isaac Newton was one of the greatest scientists of all time, a thinker of extraordinary range and creativity who has left enduring legacies in mathematics and the natural sciences. In this volume a team of distinguished contributors examine all the main aspects of Newton's thought, including not only his approach to space, time, mechanics, and universal gravity in his Principia, his research in optics, and his contributions to mathematics, but also his more clandestine investigations into alchemy, theology, and prophecy, (...) which have sometimes been overshadowed by his mathematical and scientific interests.

The question 'Why should I obey the law?' introduces a contemporary puzzle that is as old as philosophy itself. The puzzle is especially troublesome if we think of cases in which breaking the law is not otherwise wrongful, and in which the chances of getting caught are negligible. Philosophers from Socrates to H.L.A. Hart have struggled to give reasoned support to the idea that we do have a general moral duty to obey the law but, more recently, the greater number (...) of learned voices has expressed doubt that there is any such duty, at least as traditionally conceived.

Previous research shows that people can use the co-occurrence of words and objects in ambiguous situations (i.e., containing multiple words and objects) to learn word meanings during a brief passive training period (Yu & Smith, 2007). However, learners in the world are not completely passive but can affect how their environment is structured by moving their heads, eyes, and even objects. These actions can indicate attention to a language teacher, who may then be more likely to name the attended (...) objects. Using a novel active learning paradigm in which learners choose which four objects they would like to see named on each successive trial, this study asks whether active learning is superior to passive learning in a cross-situational word learning context. Finding that learners perform better in active learning, we investigate the strategies and discover that most learners use immediate repetition to disambiguate pairings. Unexpectedly, we find that learners who repeat only one pair per trial—an easy way to infer this pair—perform worse than those who repeat multiple pairs per trial. Using a working memory extension to an associative model of word learning with uncertainty and familiarity biases, we investigate individual differences that correlate with these assorted strategies.

This study investigates the impact of job satisfaction and personal values on the work orientation of accounting practitioners in China. Satisfaction with work varies across individuals and how individuals view work (i.e., work orientation) may depend not only on satisfaction with various facets of their work but also on their beliefs and values. We used the questionnaire from Wrzesniewski et al. (J Res Pers 31, 21–33, 1997) to measure work orientation. Job satisfaction was measured by the Job Descriptive Index (JDI) (...) developed by Smith et al. (The Measurement of Satisfaction in Work and Retirement. Rand McNally, Skokie, IL, 1969) and personal values were measured by the Schwartz Value Questionnaire Survey (Schwartz, Adv Exp Social Psychol 25, 1–65, 1992). Our sample consisted of 370 accounting practitioners from six major cities in China; 268 were females and 102 were males. We found that 41.9 % of the respondents viewed their work as a career, 37.6 % as a calling and 20.5 % as a job and that job satisfaction to be the highest among the “calling” group and lowest among the “job” group. There were no significant gender differences in the work orientation of the respondents. Our study showed that the value types achievement and hedonism and satisfaction with promotion were significant predictors of the career orientation, while the value type benevolence and satisfaction with the present job were predictors of the calling orientation. Dissatisfaction with work was the major predictor of the job orientation. Furthermore, length of employment was positively associated with both the calling and job orientation, but negatively associated with the career orientation. (shrink)
